摘　　要：用烧结法制备了镱铕共掺硅酸盐玻璃系列样品.测量了样品在978nm半导体激光器泵浦时光致发光谱,讨论了上转换机制.结果表明:随着镱、铕离子浓度的增加,铕在694nm红光波段光谱强度增强.镱铕离子之间能量传递主要通过合作上转换完成.A series of Yb^3＋： Eu^3＋ co-doped silicate glasses have been prepared by high-temperature melting. The photoluminescence （PL） spectra of the samples are measured （excited with a 978 nm semiconductor laser）, and up-conversion mechanism is discussed. The results show that the PL intensity of Eu^3＋ ions at 694 nm enhances with increasing Yb^3＋ , Eu^3＋ concentration. The energy transfer between Yb^3＋ and Eu^3＋ ions is achieved mainly through the cooperative up-conversion.
